Welcome to a truly one-of-a-kind, custom-built home that seamlessly blends timeless quality with a full Knez addition. Nestled on over a half-acre in Concord's Arbor Glen, this 4-bedroom, 3.5-bath Colonial offers an architectural flow and level of privacy that is simply unmatched. Begin on the inviting front porch, leading into a bright foyer. To your left and right, the formal living and dining rooms both showcase crisp crown molding, with the living room tucked behind elegant French doors. The heart of the home is the chef's kitchen, featuring updated natural cherry cabinetry, granite counters, and a huge center island perfect for gathering. This space flows into the show-stopping addition: a sun-drenched, vaulted Morning Room with panoramic views of the grounds. The main level also boasts a cozy family room with a gas fireplace and custom built-ins, a spacious laundry room, a practical mudroom, and a full guest bath. Uniquely designed with two staircases, the home offers effortless transit between levels. The upper addition introduces a dedicated office with an overlook into the Morning Room below?a workspace with energy. The primary suite serves as a retreat, offering dual closets and a spa-like en-suite with a soaking tub and walk-in shower. Three additional generously sized bedrooms share a third full bathroom. The lower level is a world of its own. The original basement houses a finished rec room, a convenient half-bath, a workshop, and expansive storage with built-in shelving. The addition's lower level reveals a secluded man cave or den with extra storage. Even the side-load garage is upgraded with a Nature Stone floor. Outside, discover a beautifully landscaped sanctuary with two patios and a Trex deck, all backing directly into a protected conservancy for permanent, wooded privacy.
